ABSTRACT:
Artificial disc replacements (ADRs) and total disc replacements (TDRs) are based upon two, directly articulating components, resulting in a restricted-motion system that better approximates more normal spinal flexion, extension, and lateral bending. One component has a concave articulating surface, and the other with a convex articulating surface. The radius of curvature of the articulating surface is smaller in the anterior to posterior direction of the ADR than radius of curvature of the articulating surface in the left to right direction of the ADR. The use of an articulating surface with two or more radius of curvature also limits axial rotation, thereby protecting the facet joints and the Annulus Fibrosus (AF). The two different radii used to create the articulating surfaces also naturally leads to an oval shape as seen from the top, which better fits the oval shape of the vertebral endplate better than circularly shaped ADRs. Both components are preferably made of a hard material and are highly polished to reduce friction.
